Defense-Grade Security Architecture & Specifications

Every vote result, incident, and command directive is recorded in an immutable append-only ledger (`pvt_result_events`). Each block contains the SHA-256 hash of its predecessor, creating a mathematically verifiable chain that prevents retroactive database alteration.

All communications traverse TLS 1.3 channels with strict HSTS pinning. Media assets, Form EC8A photographs, and confidential briefs are encrypted at rest using AES-256-GCM algorithms in sovereign, geographically isolated storage clusters.

Tenant isolation is enforced at the database kernel level through automated global Eloquent scopes (`CommandScope`). Cross-tenant data leakage is structurally impossible; an administrator in Command A cannot execute queries touching Command B.

When hostile actors employ localized signal jammers at collation points to sever 4G/LTE connectivity, Bastion automatically reroutes transmissions through encrypted 2G GSM SMS packets over dedicated priority DND-bypass telco pipes.
